SPECIIFICATION forming part of Letters Patent N o. 606,134, dated June 21, 1898. Application filed August 26, 1897. Serial No. 649,624. (No model.)

T0 all whom, t may concern: I

Be it known that I, MAX GOETZE, a citizen of the United States, residing at Sturgis, in the county of Meade and State of South Dakota, have invented certain new and useful Improvements in Spark-Arresters; and I do hereby declare the following to be afull, clear, and exact description of the invention', such as will enable others skilled in the art to which it appertains to make and use'the same.l

This invention relates to improvements in spark-arresters.

The object of the inventionis to vprovide a spark-arrester which is adapted to be used with locomotives and other engines, whereby live sparks and small cinders'shall be effectually prevented from leavin gthe smoke-stack and thusinsuring ahigh degree of safety from fire and its destructive influences.

The invention further aims to provide an arrester which is simple, durable, and cheap and one which may be readily cleaned of sub'- stances lodging therein from the combustion of the fuel. l

With these objects in view the invention consists, substantially, in the construction, combination, and arrangement of parts, as will be hereinafter fullyillustrated,described, and claimed. l

In the accompanying drawings, Figure lis a longitudinal sectional view of a'portion of a boiler having the herein-described arrester applied thereto. Fig. 2 is a top plan view of one of the screen-plates. Fig. 3 is a crosssection on the line a; x thereof.

Similar numerals of reference designate corresponding parts in the figures of the drawings.

Referring to the drawings, l designates a boiler which is provided with a smoke-stack or chimney 2,`the latter being secured thereto stack 2 and opening into one side thereof is a smoke-box 3.

The smoke-box 3 may be of any desired dimensions, and, as will be observed, projects from the stack 2. YSecured Within said stack 2 and extending from one side thereof into the smoke-box 3 is an inclined deflectingplate 4, the latter being formed, preferably, of iron, and it will be noted that as the products of combustion pass from the boiler into the stack 2 cinders and live sparks strike against said deflecting-plate 4 and are thereby caused to rebound into the boiler.

VDisposed within the stack 2 and above the deliecting-plate 4 at suitable intervals is a series of -inclined perforated deflectin g screenplates 5, 4saidp'lates being oppositely arranged and eachhaving its inner straight edge pro- 6o j ecting beyond the vertical center of the stack 2, whereby the screens are caused to overlap one another and thereby s ecure a more positive and effective separation of the live sparks and small cinders from the remaining portion of the products of combustion. The perforations in the screen-plates 5 are preferably formed in a triangular shape, and the portion of the screen-plates which is punched in order to form the perforations is bent down- 7o wardly, thus enabling the free egress of the smoke, but preventing the sparks and small cinders passing through the perforations.

Arranged above the uppermost of the perforated screen-plates 5 is an ordinary sieve 6, 75 the latter being secured to the inner side of the stack 2and in close proximity to said uppermost screen-plate, thus serving to prevent any sparks which may pass the top screenplate 5 being discharged from the stack 2.

For the vpurpose of cleaning the smoke-box 3 of any cinders which may lodge therein said box is provided with a sliding door 7, the latter being of any approved construction and preferably arranged at one side of the smokebox. If it is further desired, the stack 2 may also be provided with a similar door 8,whereby a ready entrance to said stack may be eected for the purpose of cleaning the same.

From the foregoing the advantages of the 9o herein-described arrester will be readily understood by those skilled in the art. As be- -fore stated, the products of combustion pass into thelower end of the stack 2 and contact with the defiecting-plate 4, the cinders and live sparks being caused thereby to rebound into the boiler; but it is apparent that the smoke may readily pass around the end of the deflecting-plate 4 which projects within the smoke-box and by means of the draft roo continues its passage through the stack 2, the perforated screen-plates 5 and the sieve 6 serving to further separate any destructive particles of the products of combustion, and thus render a simple, cheap, and efficient arrester.

` Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a spark-arrester,tl1e combination ,with a boiler, of a smoke-stack, a smoke-box secured to the base of the stack on the outer side of the boiler and in communication With both the boiler and stack, said stack and box being provided with doors, an inclined deiiector located in the base of the stack and projecting upwardly therefrom into the smokebox, and a series of perforated screen-plates secured-in said stack, said screen-plates being alternately arranged at opposite sides of the stack and each having its inner edge proj eating beyond the vertical center of the stack, whereby said screen-plates are caused to overlap each other and thereby eiectually prevent the escape of live sparks and the like from the stack, substantially as described.

2. In a spark-arrester,thc combination With a stack, of a smoke-box projecting therefrom and opening thereinto, a detlector disposed at the base of the stack and projecting into the smoke-box, and a series of perforated screenplates secured in said stack, said screen-plates being alternately arranged at opposite sides of the stack and each having its inner edge projecting beyond the vertical center of the stack, whereby said screen-plates are caused to overlap each other and thereby eectually prevent the escape of live sparks and the like from the stack, substantially as described.

3. In a sparkarresteigthe combination,with a stack, of a smoke-box projecting therefrom and opening therein, an inclined de'lector secured Within said stack and projecting into the smoke-box, and a series of inclined perforated screenplates also arranged within the stack, the perforations of the said screenplates being formed by punchingr the plates and bending the punched portion downwardly to permit of the free passage of the smoke but effectually preventing the egress of live sparks and the like, substantially as set forth.

In testimony whereof I have signedithis specification in the presence of two subscribing Witnesses.
